PLUG-INSERTIVNG vtroon.

Application filed May 10,

The objects of the invention are to provide eflicient and convenient means for inserting a rubber patching plug in a puncture or opening in a pneumatic tire or tube for an automobile wheel. Such casings are constructed of alternate layers of fabric and rubber or rubber compound and hence are impervious to ordinary instruments, but by means of the improved instrument the rubber plug canbe inserted or drawn through an opening in the densest'substances.

The instrument comprises a needle shaped metal tube longitudinally slotted yat its inner end to make the sides thereof compressible to engage with the stem of the plug and having a pointed outer head or extremity and provided with an annular shoulder or other engaging means, adjacent to the pointed end, which can be engaged by a suitableV tool to pull the instrument while the plug is grasped thereby forcibly through the casing, thus overcoming the resistance to its passage. n

The invention is exemplified in the accompanying drawings, hereinafter more fully described and specifically pointed out in the claims.

In the accompanying drawings, Fig. 1 is a transverse section of a casing showing the instrument in use and one form of an additional tool employed to pull it through the casing. l

Fig. 2 is a longitudinal section showing another form of the tool grasping instrument.

Fig. 3 is a side elevation of the same.

Fig. 4 is a perspective of the same;

Fig. 5 is a side elevation, and

Fig. 6 is a plan of the grasping instrument shown in Fig. l;

Fig. 7 is a transverse section of the inserting tool;

Figs. 8 and 9 are plan and edge views of a simple form of grasping instrument.

In these views A is the casing, B is a needle shaped instrument having a tubular longitudinally slotted inner end C in which the rubber' plug T is inserted and a pointed outer end D. Adjacent to this end, the instrument is provided with engaging means such as an annular shoulder E upon the head shown ien Figs. l and 2 and a tool` G maybe provided to engage with this shoulder to 1926. Serial No. 107,977.

dra-w thefinstrument through the casing. In one form of tool lugs G', G, are engaged with this shoulder to draw the instrument and plug through the puncture while the stem T of the plur is held between the arms of the slotted end C of the instrument as shown in Fig. 1.

In Figs. 2 and 3 a hook shaped draw instrument H is shown in which a keyhold shaped slot I is formed and the enlargement I through which the head is inserted is positioned upon the side of the hook, thus making it impossible for the head of the inserting instrument to be withdrawn when in use.

In Figs. 8 and 9 a. simple yoke J is shown as a draw tool, showing a transverse slot K therein open on one side. This yoke is conveniently shaped to be grasped by the hand alnd the back of the tool G is inserted in the s ot.

I -Iaving described the invention, what I claim as new and `desire to secure by Letters Patent is: j

l. An instrument for inserting a tire plug consisting in, a tapered, hollow a compressible inner end, and provided with a pointed head at its outerend.

2. An instrument for insertinga tire plug consisting in, a tapered, hollow body having a compressible inner end, and having a pointed head at the outer end,- the base of said head providing an annular shoulder adjacent 'to said outer end.

3. An instrument for inserting a tire plug consisting in, a tapered,hollow body pointed at the outer end and havingan annular shoulder adjacent to said outer end.

4. An instrument for inserting a tire plug consisting in, a tapered, hollow body pointed at the outer end and having an annular shoulder adjacent to said outer end, and a gripping device for engagingY with lsaid shoulder to dra-W said instrument through said tire.

5. A tire repairing Adevice comprising a needle having a hollow longitudinally split portion at one end thereof, a sharp head providing a shoulder at the other end of lthe needle, and a holder adaptedto engage said shoulder. l

6. A tire repairing device comprising a needle having avhollow longitudinally split body having portion at one end thereof and a portion providino a shoulder at the other end of the tapering toward the other end of the needle, needle, and .a har containing a longitudinal 10 a sharp head providing a shoulder at the slot enlarged at one portion thereof to perouter end of said tapering portion, and mit passage of said head.l f

5 a holder adapted to engage said shoulder. y In testimony whereof I hereunto afxmy 7. A tire repairing device comprising a signature. needle having a hollow longitudinally split portion at one end thereof, a sharp head HUGH T. HUGHES.
